Quick Answer: Best Litter Box for a Rex Rabbit
Rex rabbits can be litter trained just like a cat, so the right box makes house training far easier. Choose a roomy corner or low-entry pan with smooth, non-porous plastic that is simple to wipe clean every day. Our top pick is the Kaytee High Corner Litter Pan for its snug corner fit and high back that contains urine spray, while the Petmate Basic Open Pan is a strong low-entry option for larger Rex adults. Whatever you pick, keep the setup dry, because the thin fur on a Rex rabbit’s feet leaves them more prone to sore hocks and urine scald than most breeds.
Why It Matters for a Rex
The Rex coat is famously plush and short, and that same genetics leaves the fur on their hocks and feet noticeably thinner than other rabbits. Sitting on damp, dirty, or clumping litter can irritate that delicate skin and, over time, contribute to sore hocks (pododermatitis) or urine scald. A well-drained box, changed often, keeps their feet dry and comfortable. Litter training also means far less mess in the cage and play area, which most owners find is the single biggest quality-of-life upgrade for both rabbit and human.
What to Look For
Size comes first: pick a box at least 18 inches long so an adult Rex can fully turn around, with a low 3 to 4 inch entry that spares their joints and a higher back to catch spray. Corner shapes save cage floor space and suit a rabbit’s habit of toileting in one chosen spot. Place a rack of hay over or beside the litter, because rabbits graze while they toilet, and that positioning trains them to use the box consistently. Use a rabbit-safe paper or compressed-paper pellet litter that wicks moisture away from their feet.
How We Chose
We focused on boxes sized for a medium 6 to 10 pound Rex, prioritizing low-entry or corner designs, smooth plastic that resists staining and odor, and features like removable grids or high backs that keep a rabbit up and out of wet litter. We favored pans that are quick to dump and scrub, since daily cleaning matters most for this breed. Products were compared on published specifications, materials, and design rather than any hands-on research, and every pick pairs with rabbit-safe litter rather than cat products.
What to Avoid
Never use clumping or clay cat litter, which can cause dangerous intestinal blockages if a rabbit nibbles it, nor softwood shavings like pine and cedar, whose aromatic oils are linked to respiratory and liver concerns. Skip scented or dusty litters that irritate a Rex rabbit’s sensitive airways. Avoid tall-sided boxes with no low entry, and do not let the box stay wet, since standing moisture is the fastest route to sore hocks. If you spot red, swollen, or scabbed hocks, or a persistently damp bottom, consult a rabbit-savvy vet promptly.
